Hello I have a 2002 PT cruiser with 140,000 miles and a manual transmission I can hear a hiss but I'm having a hard time finding it I have used a smoke machine no leaks I have used breaking parts cleaner and spray every vacuum hose no luck the short-term fuel trim is 1%, but the long-term fuel trim is 20% suggesting a vacuum leak but I can't find it I did a compression check all cylinders are over 130 lb I am just wondering if anyone has any suggestions

And one last thing I also changed out the EGR valve and that was not the problem I'm not sure if the old one was bad or not someone just told me that that might be the problem so I went ahead and switched it out for a new one and the problem remains at the same
Please use appropriate punctuation so we can follow your train of thought. I would get a mechanic's stethoscope to pinpoint the source of the leak. Did you check that 20 year old PCV valve yet?
Sorry about the punctuation I did not realize I was taking a high school English test I have about the same punctuation you have in your comment but anyways yes I have replaced the PVC valve
Also please keep in mind that if you do not like my question you do not have to answer
I don't think he knows what punctuation is. Or a search.

Downvoting the correct answer to your question.
Just what do you want then?
Try your own link it only is a generic link to the Scotty kilmer channel I have that already
No, it is not a generic link. If you actually look at your screen, it's list of videos that Scotty made that explain how to find vacuum leaks. That is what you needed, right? I found them by typing "vacuum leak" into the search box on Scotty's Youtube channel. Sheesh.
